Research And Design Of Forest Ecological Environment Monitoring System Based On Embedded Handheld Terminal

With the development of social economy,the aggravation of environmental deterioration and the pressure of human living environment are becoming more and more serious.Environmental problems become the National People's livelihood issues.The effects of forest conservation,wind protection,sand control,climate regulation and air purification have great help to improve the human living environment.According to the current situation of the intensification of land desertification and the reduction of forest area in China,the protection of forest ecological environment is imminent,and the research of the forest ecological environment monitoring system is of great significance.The paper takes the Masson pine forest area of Xiaohe village of Baiyun town in Pingba as the research area.Through the analysis and study of the current situation of regional forest ecological environment,the requirement analysis of embedded handheld terminal forest ecological environment monitoring system is carried out.The following development contents are completed:(1)embedded system transplantation,Android system as embedded handheld terminal operating system and ITOP 4412 core as the system Develop motherboard,configure Android system boot item,kernel and file system with hardware platform,compile and transplant.(2)GIS development,the system chooses ArcGIS development component to develop GIS,and produces map,element layer,path data set and publish.(3)the application program design and implementation of the monitoring system,Android studio as a monitoring system application development tool,to realize the functions of user management design,spatial analysis,data processing and real-time data monitoring in the Android system.(4)map display optimization.We use change data structure,layer management,create Pyramid,register data source to optimize map display.(5)data processing and algorithm research,collection of environmental factors such as air temperature,air humidity,soil temperature,soil moisture,wind speed,light intensitydata,data collection,storage,upload and other operations,by removing coarse error and filtering algorithm for data pre processing to draw real time curves.In this paper,the embedded forest ecological environment monitoring system is designed and implemented.The data filtering algorithm is studied for the collected environmental data.The forest ecological environment monitoring task is completed and more effective data are provided for the relevant environmental research departments,and the data support for large data analysis is also provided.
